PROCESS FOR THE MANUFACTURE OF SOLES.

Specification of Letters Patent.

Patented June 14, 1910.

Application filed February 26, 1908. Serial No. 417,902.

To all whom it may concern:

Be it known that 1, PAUL HUHN, a subject of the German Emperor, and resident of No. 97 Tauentzienstrasse, Breslau 11, Germany, have invented certain new and useful improvements in a process for the manufacturing of soles adapted for being laid into boots, made of pressed plates of peat, of which the following is a specification.

The object of the invention relates to a process for manufacturing useful and durable soles of pure turf or peat plates to be inlaid in shoes.

The drawing discloses the method practiced. v

Figure 1 shows a peat brick in the original state. Fig. 2 shows the same after its first compression. Fig. 3 represents a circular knife cutting the compressed brick into thinner bricks shown in Fig. 4. The thickness is now inch. Fig. 5 shows a press with metal plates, between which the bricks according to Fig. 4c are inserted in order to be compressed one other time. Fig. 6 shows the mentioned metal plate with twelve of the double compressed bricks. Fig. 7 shows the brick after the double compression its thickness now being inch. Fig. 8 represents the inlay sole stamped out and Fig. 9 shows the sole covered in the usual manner with linen.

The employment of turf and peat for soles is well known but this peat was used only in form of a dust or powder in combination with an agglutinant, and further the manufacture of strong plates of pure turf or peat by pressing of peat-bricks is already well known. But such peat bricks are much too thick for soles and it is not possible to cut from this brick a plate of about inch (2 mm.). The thinnest plate which can be cut from such compressed peat brick is about inch (5 mm.). That would be too thick for soles. The invention consists therein that such a plate of about inch of thickness which can be obtained by cutting a brick of peat without causing its crumbling to pieces is again compressed till the thickness of the double compressed plate is only about inch (2 mm.). The cutting is efiected by means of a circular knife. From these double pressed turf or peat plates the felt or inlay soles are punched and covered in the usual manner with linen or the like, the edges being bound with tape.

I claim Process of manufacturing felt soles made of turf or peat plates consisting in cutting the compressed dried peat into layersof a thickness as small as can be obtained without causing the peat to crumble into pieces and in further pressing this layer to a plate of only about 1} inch (2-3 of thickness and in finishing this layer for the use as felt or inlay sole.
